leakage tests up to 3 kV or so.
I am still puzzled as to why changing the diodes improved theSo it helped but did not fixed the problem.That's the difficult part... even with the original diodes,

diodes are leaking just enough to cause such a marginal problem.
I usually do not care about keeping the stock condition if I can makeIf the diodes were the problem, then I would have expected changingI agree... I think that they're just helping to keep the whole thing cooler
So use a few of them at the same time. The heat of vaporization forWhat I might try is looking for some other part which is getting hotHmmm... That is a good idea... I`m only afraid that a bare cotton swab
most liquids is really high which is why evaporative cooling works so
well. Water is especially good but common rubbing alcohol has quite a
bit of water in it.
